[Implantation of permanent cardiac pacing electrodes by the retropectoral transvenous approach. Results of a series of 152 cases].
When the cephalic vein is unsuitable for the introduction of pacing electrodes, the retropectoral veins near the external border of pectoralis major near its subclavian attachment, approached through the same incision, may provide a suitable alternative. It was not possible to catheterise the cephalic vein in 23,8% of 756 consecutive implantations of endocavitary pacing electrodes. The retropectoral veins were looked for in 172 cases and found and used in 159 cases (92,4%). This percentage of success increased to 97,6% in the latter 83 attempts. These veins are usually very distensible. No complications or accidents were recorded. The only disadvantage was the relatively long dissection time. The stability of the pacing electrodes with this approach was excellent as reoperation was only required in 3% of cases (2 displacements and 3 exit blocks or pericardial migrations). This approach is therefore practicable in the large majority of cases in which the cephalic vein cannot be used. The multiplicity of the retropectoral veins should allow the introduction of two electrodes if sequential atrioventricular pacing were to be chosen. In addition, this approach would be useful when an atrial pacing electrode is to be added to a preexisting ventricular pacing electrode and one hesitates to puncture the subclavian vein because of the risk of damaging the electrode already in place. When direct subclavian puncture is the technique of choice of the operator, the retropectoral veins may be used when the subclavian approach is contraindicated or impossible. In any case, denudation of the retropectoral veins leads to fewer incidents than when the latter approach is used.
